Abstract Telepathology, practicing pathology from a distance, allows experts to review cases without the need to transfer glass slides. Due to significant intra- and inter-observer variabilities in the histological evaluation of Barrett’s esophagus (BE), current guidelines recommend expert consultation in cases of dysplasia. We aimed to determine whether telepathology using microscope videoconferencing can be reliably used for evaluation of BE. Biopsies from 62 patients with endoscopic findings of salmon colored mucosa extending ≥1 cm proximal to the gastroesophageal junction were randomly selected to represent benign esophagus, non-dysplastic BE, low-grade dysplasia, high-grade dysplasia, and adenocarcinoma. Three gastrointestinal-trained pathologists reviewed the cases via videoconference microscopy followed by conventional microscopy. Intra-observer and pairwise inter-observer agreements between the conventional microscopy and videoconference methodologies were calculated for each of the three pathologists using Fleiss-Cohen weighted kappa (K) analysis. The intra-observer agreement for each pathologist’s assessment of videoconference microscopy and glass slide readings showed very good reliability (K = 0.94, 95% confidence interval = 0.89–0.99; 0.88, 95% confidence interval = 0.79–0.98; 0.93, 95% confidence interval = 0.90–0.97). Mean pairwise inter-observer agreement was 0.90 for videoconference and 0.91 for conventional microscopy. Diagnosis and grading of BE using videoconference microscopy show similar reliability as conventional microscopy. Based on our findings, we propose that videoconferencing pathology is a valid instrument for evaluating BE.

BACKGROUND: Recent developments may alter the approach to patients presenting with gastroesophageal reflux disease (GERD)-like symptoms. A newly proposed Montreal consensus definition of Barrett’s esophagus includes all types of esophageal columnar metaplasia, with or without intestinal-type metaplasia. There is also increasing recognition of eosinophilic esophagitis (EE) in patients with GERD-like symptoms.OBJECTIVE: To quantify the impact of these developments on a multiphysician general gastroenterology practice in a tertiary care medical centre.METHODS: Medical charts of all patients having an initial gastroscopy for GERD-like symptoms over a one-year period were reviewed retrospectively, and audits of their endoscopic images and esophageal biopsies were performed.RESULTS: Of the 353 study participants, typical symptoms of heartburn and acid reflux were present in 87.7% and 23.2%, respectively. Less commonly, patients presented with atypical symptoms (eg, dysphagia in 9.4%). At endoscopy, 26% were found to have erosive esophagitis and 12% had endoscopically suspected esophageal metaplasia. Histological evaluation was available for 65 patients. Ten of the 65 biopsied patients (15%) met traditional criteria for Barrett’s esophagus (ie, exhibiting intestinal-type metaplasia), whereas 49 (75%) fulfilled the newly proposed consensus definition of Barrett’s esophagus. Five patients (7.7%) met the study criteria for EE (more than 20 eosinophils per high-power field), four of whom had not been previously recognized.CONCLUSIONS: Among patients presenting with GERD-like symptoms, the prevalence of Barrett’s esophagus may increase markedly if the Montreal definition is adopted. In addition, growing awareness of EE may lead to an increase in the prevalence of this diagnosis. Prospective studies of the management implications of these findings are warranted.
